Applications

Wood is one of the oldest construction materials on the planet. The earliest-discovered wood growing plant dates from approximately 400 million years ago. There is evidence that humans have been building wooden structures since the tail end of the Stone Age. Despite this resilience, wet rot can make short work of unprotected wooden structures.Wet rot poses the biggest threat to…

They can be carried out for many different reasons; to ensure the longevity of the building or structure, to reduce the long-term operating costs of heating and cooling, or to reduce the level of CO2 emissions as a result of heating and cooling. Government efforts to deal with climate change over the past few decades have made CO2 emissions a…

Depending on the type of piles used, reinforced concrete or sprayed reinforced concrete will need to be applied on top of the piles to consolidate them and provide a suitable surface for the waterproofing system. The waterproofing system used could be a cavity drainage system (Oldroyd Xv 20), a crystalline active water-proofer (Drybase Crystalline Active Tanking Slurry), or preferably a…

Drybase Crystalline Active Slurry powder is sprinkled onto the wet concrete slab after the initial set. It is then power-trowelled into the surface, imparting waterproof properties to the slab. A summary of the dry sprinkle method of application is given below:

Drybase Crystalline Active Slurry offers a solution to this problem. Because it penetrates into the concrete pile head or pile cap rather than forming a waterproof layer on top, the waterproofing material can support the loads from subsequently poured ground beams or foundation slabs. An example of a typical application is shown below, however, because piled foundations vary widely in…

Construction joints are a particular weak points in basement structures through which water can penetrate. Therefore, joints between components, including day work joints, should be durable and watertight and include appropriate waterstops (Drybase Quellmax Plus Waterbar) or hydrophilic strips. Kickers, usually cast as part of the slab, should be used to form the joint between floors and walls (NHBC Chapter…

According to BS 8102:2022, basement waterproofing system materials fall into 3 main categories (referred to as ‘Types’). Safeguard Basement Systems are combination Type A and C waterproofing systems. This means that there are multiple barriers to water ingress. In the unlikely event that one system should fail, there is always a supporting system to prevent water ingress.

The expansion caused by wall tie corrosion can force apart mortar joints – causing cracking of masonry. Other symptoms include bulging of walls and the lifting of roof edges. In severe cases wall collapse has even been reported.Wall tie corrosion is particularly common in buildings in coastal areas (due to salt-laden wind-driven rain) and in masonry that has been constructed…

First, a fillet is formed around the inside perimeter of the pond using Drybase Universal Mortar. Once the Universal Mortar has cured, two coats of Drybase Tanking Slurry are applied to the sides and floor of the pond. If a tiled finish is required, a 3:1 sand: cement render should be applied over the second coat of Drybase Tanking Slurry…

In recent years, legislation passed by the Environment Agency and the Scottish Environment Protection Agency (SEPA) has made it mandatory for most oil storage facilties to include a secondary containment vessel such as a bund which is capable of storing at least 110% of the capacity of the largest tank or 25% of the total storage capacity, whichever is the…

Materials designed for protecting drinking water-retaining structures need to meet additional requirements.

Drybase Tanking Slurry has been designed to provide protection in these demanding environments. Used in conjunction with Drybase Active Crystalline Slurry, these products can be used to waterproof sewers and sewage treatment plants in new construction and refurbishment projects.
