Gypsol Summit

We designed our Gypsol Summit specifically for use in high rise applications. In particular, where the screed needs to be pumped to ten stories and above without the danger of segregation.

Gypsol Summit; a multi-purpose screeding solution designed for use in high rise applications above ten stories

To use our Gypsol Summit in highrise buildings, you must ensure that the pump is suitable for the application, e.g. a multi-cylinder piston pump. Besides its particular use for tall constructions, this screed is also suitable for the encapsulation of an underfloor heating system, either electric or warm water.

Furthermore, you can use this to produce a smooth, flat and level floor to form the sub-base for subsequent floor coverings. It is especially suitable for internal floors in hospitals, schools, offices, apartment schemes, and other constructions.

Specially trained screeders know-how

For the best result, we advise hiring specially trained screeders to pump the screed into place. They will use specialised equipment. In conclusion, our Gypsol Summit will provide you with a cost-effective and environmentally friendly alternative to cement-based screeds.

A screed solution for every construction

To enable construction companies to always use a Gypsol screed,  we manufacture a full range of screeds that will suit every building situation.

You can choose from:

  1. Rapide; A self-compacting, self-smoothing, fast-drying floor screed
  2. Classic; Our general-purpose screeding system. The most commonly used material in our range.
  3. HTC; Gypsol HTC (High Thermal Conductivity) for use with underfloor heating and cooling systems.
  4. TS-15; An ultra-thin screed for bonded and un-bonded applications at a minimum depth of 15mm.
  5. TS-20; A thin screed suitable for bonded and un-bonded applications down to a 20mm minimum depth.
  6. XS; Extra strength material for use in heavy-duty applications, where loading is likely to be higher than normal.
  7. TimBRE; Specially formulated and tested for use in timber frame and over timber supported floors including acoustic conditions.
  8. Sureflo; Pre-blended product supplied in 25kg bags for mixing on site. Ideal where minimal quantities are required, or access for ready-mix lorries is not possible.
  9. Summit; Particularly fit for screeds pumped over very long distances or high buildings of 10 stories and above.
  10. Modular; Designed for use in modular construction to allow early movement of units, also for a lightweight steel frame and Lewis Decking.

 

Gypsol floor screed

Gypsol Summit product details

LKAB Minerals manufactures Gypsol Summit to exacting standards. We do so in quality, assured ready mix facilities throughout the UK. Also, the product is available in specific locations from volumetric on-site mixing systems.

Because we make this product from high-quality Gypsol anhydrite binder, specially selected sands and clean water, it offers the user a simple and effective floor screeding solution.

You can use this for floating, unbonded or fully bonded applications where a subsequent floor covering is to be used. Additionally, you can use the product with or without underfloor heating. And finally, it is also suitable for use in acoustic designs.

Gypsol Summit - Frequently Asked Questions

  • What is the minimal Gypsol Summit screed thickness my floor needs?

    +

    You can use Gypsol Summit screed either with or without insulation to the following minimum depths:

    • 40mm Floating Commercial
    • 35mm Floating Domestic
    • 30mm Unbonded
    • 25mm Bonded
    • 25mm cover to underfloor heating pipes
  • How soon can I lay my floor coverings?

    +

    Gypsol Summit screed dries naturally in around 28 days in right drying conditions. In case you have underfloor heating, you can commission and run this to force dry the screed. In this scenario, the screed will be dry in just 13 days. Our screed dries by evaporation of residual moisture into the air above it. Therefore, it is important to ensure your screed dries in well-ventilated conditions to remove the moisture as it evaporates.

    Additionally, it is also important that you carry out an appropriate moisture test to confirm the screed is suitably dried before applying floor coverings.
