Delivery to SIA 384/6
We execute your design exactly — and, where needed, contribute practical experience on geology, methods and feasibility. Drilling, grouting and pressure test documented to standard.
For planners, architects & engineers
Your design,
precisely executed.
Your reliable execution partner for the entire trade — from the suitability check and the drilling through to the documented handover. We deliver your sizing exactly to SIA 384/6.
What we offer planners
One trade.
One person responsible.
Drilling, probe, connection pipe and connection all come from a single source — no interface ping-pong between trades, one clear responsibility across every phase.
Suitability & permit handling
Review of the cantonal GeoHP suitability maps and protection zones, preparation of the drilling notice or building application — we support you with the submission.
The complete trade from a single source
Borehole heat exchangers, connection pipes up to the manifold, wall penetration, connection to the heating engineer — one interface instead of many.
Our own fleet for difficult sites
In-house drilling rigs on Aebi and Unimog platforms for hillside locations, tight accesses and urban sites where standard machines simply cannot get through.
SIA-compliant documentation
Borehole log layer by layer, grouting record, pressure test and handover report — seamlessly archived and handed over.
Experience & quality assurance
Over 40 years of borehole heat exchangers, the FWS quality seal — and with Mathias Broder on the FWS quality-seal commission for borehole heat exchanger drilling firms.
Working together
From pre-assessment
to handover.
-
01
Pre-assessment & suitability
Check the GeoHP map, protection zones and neighbouring probes, clarify feasibility — free and without obligation.
-
02
Coordination & feasibility
We check your design for feasibility (geology, access, method) and clarify the choice of material and procedure.
-
03
Fixed-price quotation
A transparent, binding fixed-price offer based on your design — a clean basis for your tender.
-
04
Permit & execution
Drilling notice / building application submitted, drilling with our own fleet, probe installation and grouting to standard.
-
05
Connection & documentation
Horizontal connection to the manifold, pressure test recorded, SIA-compliant handover documentation to the heating engineer.
Tender
A clean basis
for your tender.
Are you putting a borehole heat exchanger system out to tender? We provide you with the technical key data — probe type, pressure class, extraction capacity, method and reference values to SIA 384/6 — as a basis for your specifications. And we are happy to submit a transparent fixed-price quotation.
Technical basics
Everything you
need for planning.
Probe types, pressure classes, extraction capacity, grouting, frost depth, minimum distances — the technical key figures are transparently documented.
