New Service Facility
​
William Lea Ltd was recommended by Kerakoll, and brought in, by Carefoot Construction, after another screeding contractor had attempted the job with poor results.
​
William Lea Ltd was asked to remove all of the existing screed, reinstall the liquid applied (resin) gas membrane and then reinstall the self-smoothing screeds to the high standard required by the client.
​
The materials specified and used on this project were manufactured by Kerakoll.
Phase 1 - Removal of the existing, poorly bonded and failing screed
Phase 2 - Carefully exposing the existing gas membrane, ready for renewal
Phase 3 - After renewing the gas membrane and re-bandaging the construction joints with an elastomeric bandage, the deeper areas were filled (based-out) and the installation of the new screed began. The screed, Kerakoll Keratech R30, was mixed and pumped on site.
Phase 4 - Whilst laying, the screed was rolled with a spiked roller to remove any air bubbles and to help the screed self-smooth. This produced the desired very flat finish.
Phase 5 - Just 3 HOURS after laying, the screed was ready to accept foot traffic and the picture below is the Keratech R30 screed just 24 HOURS after laying.
Phase 6 - The completed Keratech R30 screed was overlaid with the resin floor finishes to leave a 'clean-room' type environment for the client.
