Applications

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…

Bund walls are normally constructed from brick or block, however where they need to contain large volumes of liquid they may also be constructed from reinforced concrete. Detailed information on bunds construction ranging from 1000 to 25000 litres can be found in CIRIA Report R163 “Construction of bunds for oil storage tanks”¹

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.

With an array of options available, it can be tricky to balance protection and durability with the desired finish.

To maximise biodiversity, a wide range of growing mediums will normally be distributed around the roof surface (usually sourced from the local area). In most cases, these are either left alone to allow the germination of wind-blown seeds, or alternatively, seeds collected from the local area are scattered over the roof area. Over time an ecosystem of plants and animals…

It should be quickly established if any contamination may have occurred, as this will strongly affect how the whole flood remediation process is handled. It should be noted that although flood water may not contain contaminants from its source, it may have picked up contaminating materials during the flood period.

However, flood resistance cannot be relied on in all situations. For example, in some cases the building structure may be unable to cope with the pressures exerted by high levels of flooding or it may simply be impractical to install flood resistance measures that can be relied upon to provide adequate protection. In these cases the alternative strategy of “flood…

Potential future flood frequency, expected flood depth and expected flood duration should be determined for the property and should inform the level of repair. Information on flood risk is available from https://www.gov.uk/check-flood-risk. Flood surveys can also be carried out by a qualified surveyor. Where there is a significant risk of future flooding, then the standards of repair will suggest improving…

During the winter green roofs keep the heat in, and in the summer they provide a relatively cool environment. Green roofs also have the ability to soften harsh edges of buildings in sensitive environments, making them blend in with the surrounding area. Turf and green roofs provide habitat for insects and other wildlife. Where new buildings are built on greenfield…
