Basement Design and Installation

Basement Solutions

SPEEDECK provide a complete specialist design and installation service providing structurally sound, waterproof, warm living spaces enjoyed by our clients.

Our individual approach to each project utilises the resource of our in-house engineers and specialist staff with extensive experience of basement construction providing cost effective robust solutions.

Our specialist and extensive knowledge of soils and structures allows us to design and implement the optimum solution for each individual project. Before making recommendations on the type of structure, construction technique and waterproofing system most suitable, we consider all aspects of underground construction including the ground conditions, water levels, environment, proximity of adjacent structures, access constraints, logistics and end use.

Every form of basement construction has different waterproofing requirements. Our waterproofing designer considers at the beginning of the design process what the form of construction will be, advising on the implications, risks, and waterproofing requirements of each form and method of construction under consideration.

Our process to producing dry basements;

Type A – Barrier Protection, where groundwater is stopped at the point of entry by the application of a waterproof membrane.

Type B – Structurally Integral Protection, where the basement structure is designed and built in such a way that the structure is watertight in its own right. This is usually done using reinforced concrete designed to BS8110, or BS8007 (see EN1992 also).

Type C – Drained Protection, where the structure allows limited groundwater to penetrate, and then diverts that water, in a controlled manner, to a point from where it is removed by drainage or pumping.

SPEEDECK install different waterproofing grades of basements;

Grade 1 for car parks

Grade 2 for any other area where absolute dryness is not paramount. Some water ingress may be acceptable provided it does not adversely affect the performance of the area.

Grades 2 & 3 do not permit any penetration of water from the ground, but define different levels internal dryness with Grade 3 being reserved normally for habitable or ‘dry’ spaces.
