Building Better Basements

Turning unused, dingy basements into warm, inviting, useable living space can be easily achieved with the wide range of products from Delta Membrane Systems. Indeed, it is possible to create basements in properties that do not already have one, and, again, the Delta range will suit this new-build construction. Delta_Quattro_copy_2Included in the extensive range is the MS-500 which is a cavity drainage membrane for use on walls and floors as a waterproofing system. Made from high density polyethylene, the sheet is made up of an 0.6mm membrane with studs measuring some 8mm deep. Available in a clear option, it gives a compressive strength of greater than 250kN/m2, and is able to drain some 135 litres/min. of water per m run. Also available is MS-20, a brown dimpled drainage sheeting with particularly high drainage capacity and substantial compressive strength, make it ideal for basement floor applications. This is also suitable for high performance seepage layers in building and civil engineering construction The Delta-MS collection also brings effective protection to foundation wall waterproofing against mechanical damage, and is suitable for both horizontal and vertical applications. One of the more recent additions to the Delta range is Delta Geo-Drain Quattro, a four-ply drainage sheet suitable for thick waterproof coatings. Quattro features a micro-perforated slip film which, together with the additional filter cloth, acts as a backup drainage layer behind the dimpled sheet to ensure that any water is drained off safely. In addition, the slip film prevents the transmission of movement to the waterproof coating. Specifically designed for flooring applications, Delta-FM protects against dampness and contamination. deltapt Traditional damp proof membranes trap moisture and hold up work while the relative humidity of the concrete takes time to drop. Delta-FM allows work to continue immediately after placement thanks to a special low stud profile. One of the applications that benefits from Delta-FM is in the installation of underfloor heating, which is becoming an increasingly popular option for the householder. To rid the basement area of any water that should collect from the cavity drainage membrane system, Delta Sump+Pump is available. Capable of collecting groundwater from a cavity drainage membrane system, Delta Sump+Pump is one option available from a range by Delta Membrane Systems.Groundwater enters via the drained cavity of the membrane system and collects through the top opening of the Delta Sump. Water is then pumped by a float-activated submersible pump to mains drainage or other suitable outlet. Delta_FM_on_air Built for durability and reliability, the system is offered with a range of accessories including high level alarms, battery back-up systems and non-return valves. Delta PT is another high quality product from the company’s range. This high performance polyethylene membrane is extruded into a series of studs to create a continuous air gap behind the waterproof membrane. On the face of the membrane is a welded mesh which allows plasters and renders to bond efficiently to achieve dry and durable finishes. Dab-fixing of board finishes is also an option. Although primarily employed in internal applications, Delta-PT can also be used externally as a waterproof support for rendered finishes especially in exposed situations, where elevations of the building are subjected to water penetrations, salt-laden air, or are simply in need of a face-lift.
