Expansion Joint Treatement
An Expansion Joint is an assembly designed to safely absorb the heat induced Expansion and Contraction of various construction materials. These joints are placed where a slab meets a building, where a slab meets another slab. They are commonly found between sections of slabs, bridges and other structures. The systems are UV resistant, highly elastic and can withstand extreme movements of the joints. Expansion Joints are installed to manage the coefficient of thermal expansion over large spans of concrete. The waterproofing material must not only cope with the movement of building, but also be designed to resist aging that leads to the weakening of bond on the concrete and causes failure of the system.
Tank & Storage Waterproofing
waterproofing for tanks prevents the tank from algae, fungus, or other bacterial growth. Pressure Grouting shall be conducted at joints. Water tanks shall be treated with either crystallization or Bituminous Chemical. Food Grade epoxy treatment can be applied for hospitals or drinking water tanks for safe Quality Water.
A waterproofing membrane is a layer of water-tight material that is laid onto a surface to prevent water leaks or damage. Waterproofing membranes generally consist of pre-formed sheets. They can be adhered to or installed around the foundations (like a structural slab) to prevent water penetration. Whether it’s to protect your building’s basement or roof, waterproofing will help stop water from infiltrating your foundation and protect your structure from water damage. Waterproofing membrane is added to the concrete that will help make water ingress impenetrable as well as making it easy to maintain.
Types Of Membranes Includes
1. Self adhesive Bitumen Membrane
2. SBS/APP Torch Welded Bitumen Membrane/
3. PVC/TPO Membrane
Swimming Pool Waterproofing
Chemical waterproofing is a methodology to arrest water ingress to any concrete structures using varities of chemicals. Some of the types of chemical waterproofing involves
1. Grout & Epoxy Injection : If cracks are forming in your concrete, you can prevent the spread and waterproof the site with a grout and epoxy injection. This is done by injecting the chemicals into the cracks, or by drilling holes into the surface to insert the material. The grout is then pressure injected and it reacts with any remaining water to form a sealant.
2. Polyurethane Coating : Polyurethane is a chemical membrane that’s primarily used to waterproof roofs and exposed areas. This is a very flexible system to apply but is best applied on flat surfaces and without elevating the moisture level of the concrete.
Considering Swimming Pool, Waterproofing should resist to both positive and negative water pressure. Need to resist to the changes in temperatures and also should resist to both acidity and alkali PH In water.
