Rise and Shine Group Qatar is one of the best Coring Cutting Contractors in Qatar
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 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 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.
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 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.
