Its our goal to develop a long lasting relationship with our clients through the quality of work and professionalism. Why is waterproofing so important? Waterproofing is a key part of the building process. NEROKERB has specialized in waterproofing since 2012. We offer a wide range of waterproofing systems for the construction industry from basement to roof. However, sometimes waterproofing problems require individual solutions. That’s why our highlyskilled technical team works together with our customers to analyze each situation in order to develop a solution which meets the individual requirements of our customers. Each year around the world, massive amounts of money are invested into infrastructure, public, and private building projects. According to a detailed survey report on damages in building structures, 80% of damages ultimately relate to waterproofing issues. Investing in high quality waterproofing not only protects construction elements against water ingress but also ensures resource efficiency, low maintenance costs, and high return on investment in the long run .
Water and moisture which seeps through a leaky roof slowly corrode the steel angles and beams which support your home. Concrete too is a porous material and waterproofing of roof is required to prevent deterioration by harmful chemicals that can enter along with water.
The use of having a sunken slab is to conceal all the pipes below the floor.It is a modern cementitious waterproofing technique that prevents leakages from sunken areas that are in constant touch with water.The floor trap and the drainage lines can be taken within the sunk portion.
Waterproofing is usually required by building codes for structures that are built at or below ground level. Waterproofing and drainage considerations are especially important in cases where ground water is likely to build up in the soil or where there is a high water table.
Water in the soil causes hydrostatic pressure to be exerted underneath basement floors and walls. This hydrostatic pressure can force water in through cracks, which can cause major structural damage as well as mold, decay, and other moisture-related problems.
Pressure grouting involves injecting a grout material into interconnected pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or solution chemical mixture. The purpose of grouting can be either to strengthen a formation or to stop water flow through it.
An Expansion Joint is an assembly designed to safely absorb the heat induced Expansion and Contraction of various construction materials. We use polysulphide method and Expansion Joint Tape Method for waterproofing this joints. is used for the safe bridging of connecting joints and expansion joints in surface waterproofing coats at moderate water loads.
Crack filling is the placement of certain material into non-working cracks to reduce water infiltration and to reinforce the adjacent pavement.We use cement based polymer modified powder material for filling cracks in plastered surfaces. It is ideal to fill 2 to 3 mm wider static cracks, it has strong adhesion and also non-shrink in nature.
APP(Atactic Polypropylene) Bitumen Membrane is more prominent waterproofing material for cement rooftops and moderate-slope terraces.With the aid of a flame, the APP membrane is put on bitumen. APP waterproofing membrane can prevent water intrusion in manufactured ponds, restrooms, water reservoirs, wall panels, and cement pathways.
PU injection grouting which is also known as polyurethane grouting or injection is used for a wide array of purposes to seal the cracks and fix the fall of plaster in concrete and masonry structures. The mixture will react and in turn, expand and toughen inside the concrete structures. This helps to stop water flowing through structural joints and cracks. It is injected using appropriate high pressure injection equipment from the “negative side”.
An anchor is a steel element either cast into concrete or post-installed into a hardened concrete area and used to transmit loads to the concrete. Cast-in anchors include headed bolds, hooked bolts (J- or L-bolt), and headed studs. Post-installed anchors include expansion anchors, undercut anchors, and adhesive anchors. Steel elements for adhesive anchors include threaded rods, deformed reinforcing bars, or internally threaded steel sleeves with external deformations. Anchor systems are typically used to connect two parts of a structure together or to connect a non-structural item to the structure.
Epoxy injection is an economical method of repairing non-moving cracks in concrete walls, slabs, columns and piers and is capable of restoring the concrete to its pre-cracked strength. Prior to doing any injection it is necessary to determine the cause of the crack. If the source of cracking has not been determined and remedied, the concrete may crack again.
Fibreglass waterproofing is considered to be one of the most popular and sought-after waterproofing methods. Due to the various features and attributes of fibre glass, this product is used in various waterproofing applications like on balconies or concrete roofs.
Areas such as bathrooms, kitchen and work areas /balconies are exposed to direct water contact from water tap connections, showers etc and remains wet for long durations. Such direct wetting and presence of high humidity causes seepage of water through the walls /floors and will result in damages to adjoining wall exteriors. The crack building properties of suitable waterproofing solutions when applied professionally will prevent damages to wet areas.
Bore packing is one of the preparatory works for waterproofing. This is to be ensured in Plumbing and Electrical penetrations. It is the process of fixing Plumbing pipes in RCC members (Slabs or beams or RCC walls) in their cutouts / core cuts.
Swimming Pools and Water Tanks are subject to enormous hydrostatic pressure on their walls and floors. Furthermore, swimming pools at /below the ground level are also exposed to moisture from soil on the exterior walls. These adverse factors will affect the strength of the structures and results in leakages. Use of elastomeric, crack bridging waterproof protective coatings which can resist high hydrostatic pressures need to applied on such structures to prevent leakages.
