Insulated Raft Foundations in Wales
ISOQUICK projects in Carmarthenshire and Newport, and what its Kiwa certificate says about the Welsh Building Regulations.
ISOQUICK has been used on public-sector and residential projects in Wales, including two of the three new primary schools built for Carmarthenshire County Council by Lloyd and Gravell.
Projects in Wales
Gorslas School
One of three new primary schools built for Carmarthenshire County Council, alongside Kidwelly School and Ysgol Y Castell.
The ISOQUICK base covered approximately 1,200m² and was installed over three days by a team of three.
The simple shape and efficient form factor meant that only 150mm of ISOQUICK was required, providing the shutter for a flat 250mm concrete slab.
Kidwelly School
Another of three new primary schools built for Carmarthenshire County Council.
A similar size to the Gorslas School project, the ISOQUICK system was installed over the same three-day window, this time using the lighter IQ-60e grade of material.

Building Regulations in Wales
Kiwa BDA Agrément certificate BAF-20-179-S-A-UK lists the following requirements of the Building Regulations 2010 (Wales) as ones the system can satisfy or contribute to satisfying:
- A1(1) Loading
- C2(a) and C2(c) Resistance to moisture and condensation
- L1(a)(i) Conservation of fuel and power
- Regulation 7(1) Materials and workmanship
- Regulation 26 CO₂ emission rates for new buildings
- Regulation 26A Primary energy consumption rates for new buildings
- Regulation 26B Fabric performance values for new dwellings
Kiwa's certificate states that the system, if installed and used as set out in it, "can satisfy or contribute to satisfying" these requirements, and that it does not confer compliance of any project-specific design. Your designer or building control body confirms compliance for your project.
Certification and technical data
ISOQUICK holds Kiwa BDA Agrément certificate BAF-20-179-S-A-UK, which is valid across England, Wales, Scotland and Northern Ireland. Floor U-values depend on the grade, the depth of under-slab insulation and your building's perimeter-to-area ratio; see the U-value tables. If you are choosing between systems, our comparison of UK insulated foundation systems sets out what each supplier publishes.
