GRP LINING

1/3

GRP Lining is a significant application in the fiberglass industry. It has diverse applications including corrosion resistance, structural strengthening and waterproofing. It can be found in most if not all water storage tanks, sewerage tanks, chemical storage tanks, tank roof lining, manholes, sewerage sump pit, cooling towers, chemical plants, firefighting networks, pipeline networks and water transmission pipelines etc..

Special grade resins are used to attain various properties which allow the GRP Lining to withstand resistance to fungi & algae, strong acids chemical and high temperature. It is an effective alternative to component replacement.

GRP Lining will completely and seamlessly seal the cracks, leaks, corrosion and flaking materials. It offers a new life to damage/eroded walls providing a long term, secure environment at a fraction of the cost of total rebuild.

CORING & CUTTING

1/5

Core drilling:
Core drilling is favoured by many contractors due to its reduced vibration and noise levels meaning work can be carried out with very little inconvenience to others in the environment (Offices, Hospitals, Airports or Domestic Properties). The work can be carried out wet therefore making it a fast and clean method of creating a perfectly formed hole ranging in size from 6mm up to 900mm in diameter.

The holes are drilled to your requirements, plus another financial benefit is that the labour required to carry out any making good is vastly reduced, as the structural integrity of the building/structure remains virtually untouched.

Core drilling is carried out using either electric and hydraulic equipment. Both types of equipment can be fully self-sufficient. Should a power supply not be available on site, we can easily provide generators, and petrol or electric hydraulic power packs.


Wire sawing:
Wire Sawing is a versatile method of cutting where other methods are not practical such as cutting out mass concrete, removing plinths, bridges and staircases.

It can also be used to flush cut to existing walls. The big advantage of wire sawing is that there is basically no limit to the depth or shape that can be cut.

WallSaws:

Wallsaws solutions are used to cut reinforced concrete walls for a variety of applications such as openings for new ventilation ducts, windows, and doorways or just to reduce the height of existing walls.

We can also be used to cut floors where access for a conventional floor saw is restricted such as stairwells, or where the gradient is too great making it impossible to safely control a floor saw. This solution can be used either inside or outside and can cut to a depth of 725mm.                              

The wall saw is powered by a high frequency electric unit with remote controls for the cutting head enabling a single operator to safely and efficiently carry out the cutting from up to 10 metres away.

Re-bar Detection:

We are specialist in Re-bar Detection service; this service is a non-destructive structural analysis to find locations of rebar or hollow cores in concrete. We can provide full reports to building owners and engineers to show location of rebar, size, cover and spacing’s. Alternatively, we can mark the re-bar on the concrete to assist with concrete cutting and drilling.

What is firestopping?

Firestopping solutions are used, in combination with a various range of materials and components, to seal joints, openings and penetrations in fire rated resistance walls, or floor systems. Firestops are implemented to restore the fire resistance rating and maintain the fire resistance qualities of such passive fire protection systems, reducing the spread of fire and filling the penetrations with fire resistant methods and products. Unprotected openings in fire separations make your fire resistance wall obsolete in terms of fire resistance rating, and ultimately provide fire an unimpeded route to spread and damage your assets. Structures are built with fire rated resistance walls, barriers, partitions and floors which allows fire compartmentation of the building. However, joints between penetrations or entrances in passive fire protection systems can nullify the security they were implemented to make. RSIE & SHINE firestopping solutions are devised and built as vital parts to passive fire protection. We can provide you an extensive line of fire protection items sealants, intumescents, gadgets and shaping material to legitimately seal joints and entrances, guaranteeing the execution of the fire-fire rated passive fire protection system. RSIE & SHINE work with you and fire engineers to understand whether or not the penetrations in fire wall or floors will remain permanent fixtures. Some fire stopping penetrations can alter during renovations or retrofitting in your building and may require new electrical systems – which needs attention from experienced experts in maintaining your fire resistance rating and passive fire protection systems.

Fire rated wall, barrier, and floor opening types

Unprotected fire separations defuse the functionality and resistance rating of a passive fire protection. What to look for:

  •  Electrical through-penetrations

  •  Mechanical through-penetrations

  •  Structural through-penetrations

  •  Unpenetrated openings (openings for future use for example)

  •  Re-entries of existing firestops

  •  Control or sway joints within fire-resistance rated wall or floor assemblies

  •  Junctions between fire-resistance rated wall or floor assemblies

  •  "Head-of-wall" (HOW) joints, where non-load bearing wall assemblies meet floor assemblies

Why is firestopping critical to passive fire protection?

Insufficient firestopping of fire wall opening penetrations can allow fire to penetrate fire cells, while incorrect material selection or poor installation can severely reduce the fire resistance rating of the firestopping seal.

 

Unprotected fire wall, barrier and fire resistance system penetrations provide one of the major contributing cause of the rapid, erratic spread of smoke and fire in your building. However, to ensure your facility, occupants and assets remain safe, fire stopping and fire sealing techniques can maintain your passive fire protection systems and reduce the severity of the impact of fire.

 

Fire stopping pertains to several key elements for maintaining a passive fire protection system. The two basic types of penetrations are: 1) A through penetration is a hole made in a fire-rated wall or floor to run pipes, cables or any type of building service, completely through from one side of the fire barrier to the other; and (2) A membrane penetration is a hole in one side of a fire-rated wall or floor for a single surface-barrier penetration. (i.e., an electrical outlet/switch box).

Firestopping installation methods

RSIE & SHINE Fire Protection are your firestopping installation experts. Most fire- stopping products engage intumescent materials that, when exposed to heat, expand to fill any cavities in the fire wall, barrier or floor opening penetration. Usually, these products include fire-stop mortar, caulk, putty sticks, blocks and pillows.

 

Firestop mortar and caulk are semi-permanent products and are generally applied to the penetration with a hand-held caulk gun while mortar products are applied with a trowel.

 

Firestopping putty sticks are moulded around the cables, conduit and pipes that penetrate the fire-resistant system. Fire-stop blocks and pillows that contain intumescent material can also be installed, stacked and formed to fit into large opening penetrations.

 

Where a cable tray finishes at the wall and a conduit sleeve penetrates the wall to offer a path for cables, RSIE & SHINE will implement a fire stop around the conduit penetration and seal the conduit body with fire-stopping material.

 

RISE & SHINE also have the expertise, tools and resources to replace damaged firestopping systems and maintain firestopping regulations and compliance procedures for all installations.

Firestop systems

  •  Firestop block and plug – designed for retrofitted cables.

  •  Firestop foam – seal pipe and cable penetrations, from small to medium sized applications.

  •  Firestop cast-in and sleeve – specially designed for pipe penetrations through fire-rated floors.

  •  Firestop collars, wraps and bandages – protect all of your piping penetrations

  •  Firestop sealants & sprays – firestopping solutions for walls and joints between floors and walls.

  •  Firestop cable protection – cable protection to reduce flame damage.

  •  Firestop coatings systems, cushions and mortars – combustible and non- combustible pipe and insulation materials, to firestop penetration seals.

FIREPROOFING

INTUMESCENT OR CEMENTITOUS PROOFING FOR STRUCTURAL FIRE PROTECTION

The most common use for intumescent paint in architecture is to provide an aesthetically pleasing finish on exposed structural steel members.

  • Typical spray applied fireproofing provides a thick and spongey surface that requires a finished surround to hide and protect the steel member. Intumescent paint provides the same level of protection in a coating that looks like a thin layer of paint.

  • The paint product is applied to the steel in layers as needed to generate the thickness that corresponds to the level of protection mandated by the building code. A final layer of intumescent paint is mixed with pigments that provide the desired finish colour for the steel.

  • Intumescent coatings, referred to as intumescent paint, are used in buildings as a passive fire resistance measure. They can be applied to structural members as an aesthetically pleasing fireproofing product. The key feature of intumescents is that they expand significantly when exposed to high temperatures, such as those found in a fire. Some intumescent products can expand to more than 100- times the original thickness. As the product expands it becomes much less dense, which makes it act as in insulator that keeps the high temperatures away from structural members or protected openings.

CHEMICAL ANCHORING

1/4

What is a Chemical Anchor?                

Chemical anchoring is a technique for fastening to concrete and similar substrates that provides more flexibility than mechanical anchoring. A mechanical anchor, such as a sleeve anchor, wedge anchor or drop-in anchor, is inserted in the concrete and expands upon tightening. This expansion causes the anchor to grip the wall of the hole and provide an extremely strong hold. Whilst being a very popular and economical option, there are, however, some limitations.

So, what is a chemical anchor’s advantage?                                                                                      

With chemical anchoring, a resin is injected into the hole prior to insertion of the stud. With this, the chemical naturally fills in all irregularities and therefore makes the hole airtight, with 100% adhesion. This extra adhesion creates extra strength.And with mechanical anchors, each predetermined size—length (embedment) and diameter—has its own load capacity limits. Chemical anchors have virtually unlimited embedment depth, so you can embed any length of rod into the hole to increase the load capacity. And if you choose to use a larger-diameter hole with a thicker rod, you increase load capacity again.

Chemical anchors — also known as chemical studs—can also be placed towards the edge of concrete substrates and through masonry block. The non-expanding nature of a chemically-held rod drastically reduces the chance of the surrounding concrete cracking. This is very good for securing railings on to shallower slabs, or concrete stairs, and similar applications. Finally, chemical anchoring gives you the opportunity to make slight adjustments to the stud’s alignment while the chemical is curing, whereas a mechanical anchor needs a hole to be drilled millimetre-perfect every time, and if it isn’t, it cannot be used.

The downside of chemical anchors, to some contractors, are that they are more complicated to install, and incorrect installation habits can jeopardize the anchor’s capacity. Following correct installation methods are critical, Allfasteners offers training and instruction in this. They may also be considered more expensive than mechanical anchors. However, apples should be compared to apples in this instance, as both fasteners are often used for very different things, especially when satisfying engineers’ requirements. Seek advice on this, if there is ever any doubt with what to choose.
