BEGRID WP WAB Heat Pump Foundation

BEGRID WP WAB Foundation for Heat Pumps (without Concrete)

The BEGRID WP WAB heat pump foundation is a modern and time-saving alternative to the classic concrete foundation – ideal for the secure installation of heat pumps outdoors. The pre-assembled complete solution does not require concrete and lengthy curing times and is immediately load-bearing. This makes it perfect for builders, installers, and professionals in landscaping who value easy assembly and sustainability.

Advantages at a Glance

✅ No Concrete Work Required: A gravel and chippings bed replaces earth and concrete work, saving time, effort, and costs.

✅ Quick Readiness for Use: After assembly, the foundation is immediately usable, eliminating long waiting times.

✅ High load capacity: The robust ground grids made of high-quality plastic provide a stable base that is also suitable for heavier heat pumps.

✅ Integrated vibration damping: Special damping bases absorb vibrations, reduce noise, and protect the machine.

✅ Weather and UV resistant: Weatherproof materials ensure long-lasting outdoor use.

✅ Recycled material: Made from recycled plastics.

System Components

The BEGRID WP WAB Set includes everything needed for a secure foundation:

• 2 ground grids (each 80 × 40 cm) with high pressure and deformation stability

• 64 paving stones for weighting and aesthetic design (standard color gray, special colors on request)

• 2 vibration buffer bases with mounting profile

• 4 fastening sleeves with ground anchors for secure hold of the heat pump

Easy Installation

The construction of the heat pump foundation is simple and can be completed in a short time:

1. First, the ground is excavated to a depth of about 25 to 40 cm to create a load-bearing base.
2. A layer of gravel (grain size 0/32) with a thickness of 20 to 30 cm will be introduced into the excavation and thoroughly compacted. On top of this, a level gravel bed with a height of approximately 5 to 10 cm will be created.
3. The highly load-bearing plastic ground grids with already integrated vibration dampers are precisely positioned on the prepared gravel bed.
4. At the diagonally opposite corners of each ground grid, individual paving stones are removed to  drive in the ground sleeves. Subsequently, the anchor plates are inserted and the paving stones are replaced.
5. Finally, the heat pump is aligned on the pre-assembled damping elements and securely fastened.

Detailed documentation for installation is, of course, available upon request in advance or with the order.

Why BEGRID WP WAB?

Compared to traditional concrete foundation solutions, this system significantly reduces the need for heavy materials, disposal effort, and construction time. At the same time, functionality is maintained: a stable, load-bearing surface for heat pumps with optimal vibration damping.
