Basement Waterproofing - London

 

Remit

 

AP Gooch LTD won this contract to design and install a waterproofing system in this iconic building near Tower Hill, London which was to be converted into a gymnasium. 

 

Outcome

 

AP Gooch's very own CSSW Surveyor decided to use a combined system using a Type A waterproofing system over the existing soffits. The steels were grit blasted and sprayed with reinforced concrete to give strength and protection for years to come. The soffits were grit blasted and coated with two coats of Vandex BB75E and protected with waterproof renders. The floor slab and upstand were designed in conjunction with engineers calculations to comply with the British Standards. 

 

The walls and floor had a Type C Cavity Drain System installed in conjunction with BS8102 2009 with two sump chambers containing a dual pumping system. This project was over 500 square meters and completed in 4 weeks.

Basement Conversion - Bolton

 

 

Remit

 

The owners of this 3 storey property wanted to increase living space but couldn't extend due to lack of land at the rear. The property benefited from having an original basement that was currently being used for storage. It was an ideal opportunity to convert the basement into the extra space required. 

 

Outcome

 

The basement required small structural alterations relating to lintels above openings before a new concrete slab was poured. ULTRA 8mm Membrane was applied to the walls with ULTRA 20mm Membrane being laid on the floor. An ULTRA Twin Sump Pump has been fitted to remove the water that reguarly enters the basement.

New Build Garage Waterproofing - Lancashire

 

 

Remit

 

A large garage, designed to house several vehicles was to be built into a hillside. External waterproofing was to be applied but the owner was advised to have an internal Type C cavity drainage system installed as access for maintenance externally was difficult.

The internal walls were covered by ULTRA 8 Membrane with ULTRA Drainage Channel installed around the three retaining walls. The floor will be covered by N-Virol Epoxy Floor Seal.

As the front of the structure is open (not underground) there is no need for a pump. Any water ingress will fall by gravity into the outside groundwater drains.

 

 

Materials Specified

 

• ULTRA 8 Membrane 2.4mtr x 20mtr

• ULTRA Silver Brick Plugs and Seals

• ULTRA Double Tape

• ULTRA Drain Channel, Inspection Ports

Basement Conversion - Chorley, Lancashire

 

 

 

Remit

 

This property is built into the side of a hill and has three earth-retaining walls.

The clients complained of water running down the walls during and after heavy rainfall. The owners wanted to turn the unused basement into a more habitable living space which could incorporate a large open living area. They also had the intention to sell the house in the near future and with the added benefit of extra living space in the converted basement, it will hopefully add significent value to the property.

 

Solution

 

The contractor was asked to carry out the initial groundworks, the relevant structural waterproofing and the interior fit out upto decoration stage.

As the property was not completely underground, it did not require a pump system. However, drainage channel was installed around the floor perimeter to deal with the water ingress. The drainage channel leads to the rear of the property and into an external soak-away.
