Raised floor cost prohibitive
Le problème
Raised technical floor: 80 to 150 EUR/m², incompatible with economical renovation.
Sept Tools
Desman brushless 1600 W: direct slab recessing, cost divided by 5.
Sept Tools
Professional concrete floor grooving
Brushless floor chasers for straight cable grooves, recessed cabling and technical paths in concrete slabs.
Concrete floor grooving is a less frequent operation than wall chasing, but it appears systematically in indoor underground network projects, data centre technical paths and electrical renovation of older buildings. Groove accuracy conditions cable installation, patch quality and final sealing. Sept Tools offers two brushless floor chasers sized for intensive professional use.

Challenges and solutions
Technical challenges and answers
Section too wide for grinder
Le problème
Multilayer and drainage 32 to 60 mm: angle grinder requires two passes and crosscutting.
Sept Tools
Taupe 60 mm in one pass: width set, brushless throughput preserved.
Irregular joint width
Le problème
Joint profile demands constant width: variation means infiltration and costly rework.
Sept Tools
Guided Desman: constant width across 50 linear metres, IP65 precision.
Data centre electrical compliance
Le problème
Earthing out of tolerance: audit failure, data centre not certifiable.
Sept Tools
Calibrated brushless 1600 W chase: precise trace for compliant anti-static network.
Uncaptured floor silica
Le problème
Floor chasing without extraction: concentration 300x OEL 0.1 mg/m³, critical exposure.
Sept Tools
IU33 Longopac HEPA H13: source capture, exposure divided by 50.
Blade stall in rebar
Le problème
Carbon blade on rebar: overheating, stall, blade break, operator risk.
Sept Tools
Brushless 1600 W constant torque plus anti-jam plus dedicated diamond blades.
Use cases
For which job sites?
Office renovation cable recessing
Recessing power, low-voltage and fibre in existing slabs for offices and hotels. Economical alternative to raised floors: 60 to 100 linear metres per shift.
Industrial screed plumbing
Drainage and supply networks in existing screeds for food processing and pharma sectors. Taupe handles sections up to 60 mm, 40 to 70 linear metres per shift.
Warehouse expansion joints
Creating or refurbishing expansion joints on industrial and logistics slabs. Constant width across the full run: 30 to 50 metres per shift depending on section.
Data centre anti-static earthing
Recessing earthing cables for electrical compliance in server rooms. Millimetre-precision trace: 50 to 80 linear metres per shift.
Frequently asked questions
Your questions, answered
What is the difference between Desman and Taupe?
The Desman handles narrow chases from 5 to 30 mm for cabling. The Taupe covers wider sections up to 60 mm for plumbing tubes. The two machines complement each other to address every floor chasing need.
Can I groove a damp screed?
Yes, provided the screed is firm. The IP65 rating protects the machine from residual humidity, but a fully fresh screed risks sticking to the blades.
How can edge chipping be avoided?
A steady feed rate and an appropriate blade prevent chipping. Sept Tools supplies specific diamond blades for hard and reinforced concrete depending on the substrate.
How many metres per blade?
On standard concrete, expect 80 to 120 linear metres per blade. On reinforced or very hard concrete, lifespan drops to 40 to 60 metres. Blades always in stock in Roanne.
Is there a jamming risk?
The brushless motor includes protection electronics that cut rotation on blockage. The machine restarts on trigger release, with no risk to operator or mechanism.
