Deltas Damp Proofing brochure summarizes key messages for homeowners, architects, specifiers, developers and contractors offering solutions to prevent and reduce dampness in structures and ways to remove damp and mould once it occurs. More than a sales magazine, we believe our Damp Proofing brochure effectively showcases great products through truly inspiring design. This 40-page document has been artistically designed simply and effectively to guide you from design philosophies to remedies available.

Deltas newest edition of brochure offers architects, specifiers, developers, contractors and homeowners advice on continuous waterproofing solutions. In its most basic form, Deltas newest edition is instinctive - a wet basement requires remedial works, if there is an active leak, it requires stopping whilst it is understood that there are numerous waterproofing solutions available, are these systems and solutions continuous and able to withstand the test of time and offer durability to the structure life cycle? The main objective of this brochure is to provide some steps that can be immediately followed in any kind of structural waterproofing project to reduce the risks, to facilitate understanding and to improve the expected results.

Perimeter drainage channel for basement waterproofing (Type C) Cavity Drainage Systems. It can be used in most waterproofing situations and is particularly suited for use in conjunction with Delta MS 20 & MS 500 Cavity Drain Membrane Systems.

The Dual V3 packaged pump station has been specifically designed to work in harmony with the Delta Cavity Drainage System to collect Ground Water via a perimeter channel or 110mm pipe (129 Detail). Pumping applications are invariably demanding typically operating in unsympathetic, arduous or extreme environments, where quality matters. The Dual V3 sump offers unrivalled capabilities.

The Delta Dual V4 packaged pump station has been specifically designed to work in utility with the Delta Cavity Drainage System to collect ground water. Suitable for larger floor areas of up to 150m2 and or a surface area of up to 12m2. Where larger surface areas are involved the drainage capacity of a sump chamber and discharge flow rate of the pumps become greater. The delta Dual V4 Sump Pump system offers a flow rate of 3ltrs per second to a pumping height of 3 meters but with a maximum pumping head of 7 meters.

The Delta Dual V6 Sump & Pump Unit is designed for use in deep basements, basements of more than one storey or where long discharge runs are required. The Dual V6 are upgrades to the standard Dual V3 sump pumps where higher discharge heads are required. They can collect groundwater from a cavity drainage membrane system and light wells that totals up to 12m². Groundwater enters via the membrane system and drainage channels and collects through the top opening of the sump or via three 110mm pipe inlets. The water is then pumped via two powerful V6 float-activated submersible pumps to mains drainage or another suitable outlet.

The document applies when a construction product is covered by a harmonised standard or conforms to a European Technical Assessment. The DoP details the product and the standard and contains information about its performance in relation to the essential characteristics defined within the applicable harmonised technical specification. As from 1July 2013 CE marking must be applied to a product which has either a current DoP or apreviously issued Declaration of Conformity (DoC) under the Construction Products Directive (CPD). The manufacturer through provision of a DoP assumes legal responsibility for the conformity of the product.

DualProof is a Type A waterproofing pre-applied, sealed two layer highly flexible PVC membrane laminated with a non-woven PP-fleece, composite waterproofing membrane which forms a permanent mechanical bond with freshly poured concrete preventing the tracking of water between the waterproofing membrane and the concrete sub-structure.

The Delta Hi-PowerMaxx provides battery backup for larger pumps such as the V4, V6, Foul and Bespoke V3 basement pumps when there is a loss of mains power. If the pump loses power, the battery backup system kicks in and keeps the pump running (see spec for guidance on cycles per pump on the battery back up system). This allows the sump pumps to continue to safely discharging water from a basement even during a power cut. This battery backup is specifically designed to run one or two V4, V6, Foul and Bespoke V3 basement pumps without mains power. When power fails, the pump(s) automatically take power from the Delta Hi-PowerMaxx. This battery backup will have been fully charged during mains operation. It will automatically recharge when mains power returns.
