Concrete works

Concrete and reinforced-concrete works for foundations, slabs, and monolithic elements — with testing and documented protocols.

Approach

Concrete quality is not visible to the eye. It only shows up after cure and under load. So we make testing documentation part of execution, not an add-on. Pour does not start until formwork, rebar, and mix have been checked off.

We work on small foundations and on monolithic floor slabs and larger structural elements alike. Every site has one accountable concrete lead responsible for mix quality, pour pace, and surface finish.

Workflow

Six stages — from substrate preparation to strength classification.

Substrate and formwork design
Foundation excavation or slab substrate, level and grade check. Formwork drawings per pour height.
Formwork install
System formwork (Peri, Doka) or panel formwork per site conditions. Shoring check with engineering sign-off above 2 m.
Rebar placement
Mesh or bar installation, anchorage, cover check before pour. Photo-documented protocol.
Mix intake and pour
Strength class, slump, and temperature checked at the pump. Test cubes taken on every pour. Vibration, no exceptions.
Cure and aftercare
Moisture retention per temperature. Winter works only with heated formwork or insulation blankets.
Tests and acceptance
Cube test at 7 and 28 days, written report. Formwork strip only after required strength class.

Classes and standards

Concrete class
C25/30 default for foundations and slabs; C30/37 or C32/40 for high-load elements. Frost resistance F150 for exposed sites.
Reinforcement
B500B rebar to EVS-EN 10080. Cover 30–50 mm per exposure class (XC, XF).
Mix suppliers
Rudus, Betoneks, or HeidelbergCement — with batch ticket, not a "local call".
Surface flatness
Floor slabs to SR1 (3 mm/2 m) with trowel finish. Power-float to SR2 or better on request.
