ICS offer a full range of cellar tanking systems to suit both commercial and domestic
applications. In situations where there is no water pressure the most cost effective
solution is the plastic studded membrane system. ICS Ltd are approved Contractors for the
Spry Seal Studded Membrane System. The benefits of this system and further information as
follows:
What is Spry Seal
Spry Seal is a system for damp and water-proofing rooms and structures.
At the system's heart is the Spry membrane - a studded sheet made from high density
polyethylene. This highly impermeable plastic membrane acts as a barrier to moisture,
allowing you to have completely dry and fully versatile internal floor and wall surfaces,
and so make full use of cellars, basements, or any other areas where dampness and moisture
are problems. Spry Seal membranes are also suitable for use as part of a control system
for ground gases such as radon & methane.
How does it work?
The beauty of the Spry Seal system is that, in internal applications, it does not simply
hold back water (and thereby risk merely transferring the problem elsewhere).
Instead, the studded construction of the membrane enables it to work in three ways. First
it acts as an effective barrier to dampness. Second it creates an air gap next to the damp
surface, allowing it to breathe, and creating an air flow across it - helping to dry it
out out. And thirdly, Spry membrane provides an effective and efficient drainage system,
preventing the build up of moisture.
This triple action makes Spry Seal a highly efficient, convenient and cost-effective way
to control dampness and make the most of previously unusable cellars and basements.

Dry lining over the Spry
membrane provides a fast, simple and versatile finish.
The membrane is fastened to the wall using Spry sealed nylon fixings. Timber battens are
attached, often by screwing them into the threaded fixings, so as to ensure that the
membrane remains sealed. Finally, Plasterboard is fixed to the battens, providing a clean,
dry, insulated interior surface. |
How is it used?
The membrane is unrolled with its studs against the damp surface and held in place using
special sealed fixings. Joins in the membrane and any openings (for pipes etc) are made
watertight with sealing tapes. Gaps will sometimes be left at an edge to allow the air
space behind the studs to be vented into the room, or else it may be vented into the
outside atmosphere through air bricks. Where there is a great deal of moisture, or running
water, a completely sealed system may be used, without vents into the room. This can be
augmented with drainage gullies or pumps below the membrane. Once the membrane is in
place, battens can be affixed (using sealed fixings) and dry lining erected inside it. |
