Screed Products :

Standard Liquid Screed:

This is the most commonly used product. It offers excellent compatibility to underfloor heating systems as well being able to be laid thinner than a traditional dry cement screed. It can be laid in very large areas without any control joints and can be worked on after as little as 2 days after being installed. It offers a curing time of up to 1mm per day up to a depth of 50mm. Anything over that depth is then reduced to 0.5mm per day.

Fast Drying Liquid Screed:

This is becoming a more popular product as it offers everything a Standard Liquid Screed does but reduces the drying time by up to half. This means it offers a curing time of up to 2mm per day up to a depth of 50mm. Anything over that depth is then reduced to 1mm per day

XTR Liquid Screed:

This is an extremely strong liquid screed which is ideal when the floor needs to be laid thinner than normal. It is also used in high foot traffic areas. It has the same drying speed as the Standard Liquid Screed.

Floor Preparation :

We offer a floor preparation service prior to any underfloor heating and/or screed being laid. This includes installing a full radon/gas barrier to NHBC/Building Control standards.

We can then install all the required insulation ranging from PIR, Jablite and Platinum Ground Floor or even sound control layers like Yelofon HD10 or acoustic rubbers like Isorubber.

We also install perimeter edging foam around the entire building. This usually comes with the underfloor heating kit but can be supplied by ourselves if required.

Lastly we also install a layer of plastic between any insulation and the liquid floor screed itself. This is essential as it acts as a barrier between the two preventing any reaction as a result of the insulation and screed touching each other.

We then tape all joints in the plastic, seal around any pipes/cables coming up through the floor and secure it to the perimeter edging foam. All this is required to prevent any screed leaking into any gaps and getting under the insulation causing it to float up.

Grinding :

Grinding the floor is a necessary step if any bonded floor surfaces are to be applied to the finish screed. It involves removing the top layer of screed. This layer forms as the screed dries and the water rises to the top. It is a dusty layer that prevents anything from being stuck to the actual floor. Once it has been removed it allows moisture to leave more readily which in turn speeds up the drying process. It also means that any flooring surface that is now bonded to the screed will not become unbonded due to the laitance releasing at a later date.

Moisture test :

Before any floor finishes are laid the screed needs to be fully dry. The most accurate way to test this is by using a Carbide Bomb test. This involves taking a small sample of floor and placing it in a pressure vessel with some chemicals. The chemicals then react with any moisture in the screed and give a highly accurate reading. If the floor is not dry prior to floor coverings being laid the residual moisture in the floor may cause the floor coverings to debond from the floor.
