Sylfaen® Foundation System
![]() |
Simply put, Sylfaen is the Welsh word for foundation. Tŷ-Mawr’s LABC Approved Insulated Foundation Systems allow for the use of a reinforced concrete slab or if preferred, a limecrete slab (as used in the extremely successful sublime® system). Sylfaen® is an Insulated Foundation Systems use Glapor’s® high-performing SG 600 100% recycled foamed glass gravel (RFG) to construct a load bearing, thermally insulated foundation – a simple, fast, construction that offers substantial time advantages as well as high insulation values and potential cost savings. |
Ty-Mawr has developed a system using Glapor® Gravel as an insulating hard-core for use in foundations. Insulation is provided directly by the SG 600, and the greater the depth of the SG 600, the greater the insulation value. It is easy to insulate to Passive House (Passivhaus) standards using this high-performance gravel from Glapor®. If necessary radon gas protection can be provided by the use of a radon barrier or ventilated sump. Please check requirements with your local area Building Control Officers. As Glapor® is free draining, the examples shown do not include a damp proof membrane (DPM). It is possible to include a DPM if desired, depending on local ground conditions |
As can be seen in the diagram below, a reinforced concrete slab (limecrete is too weak for this purpose) is placed on a bed of compacted Glapor® Gravel. As Glapor Gravel can withstand a compressive force of 60 tonnes per square metre it is possible to construct a 5-storey building using this method. Sylfaen® has been rigorously assessed by Structural Engineers, Price & Myer. They were given the brief of assessing Sylfaen® in the worst soil conditions possible for use, their assessment is available on request. All sites should be assessed on a case by case basis by a structural engineer before construction starts. |
