Ceiling grooving is the critical step of routing networks inside suspended ceilings and soffits. Tertiary electrical cables, suspended HVAC lines, fibre optics, home automation: every recessed metre goes through a ceiling chase. Done manually with an angle grinder or chisel, the operation is punishing, loud and non-compliant with silica OELs. Sept Tools offers a dedicated set: the Desman RAI102822 mounted on an articulated arm with Eland trolley to absorb the weight. The operator guides the machine without carrying it, the articulated arm compensates for the weight at all times, and source extraction delivers silica compliance and a clean site.

Challenges and solutions
Which challenges, and how to solve them?
Desman weight overhead ELV
Le problème
Chaser held overhead: ELV exceeded in 2 h, strain assessment mandatory.
Sept Tools
Articulated arm fully compensates weight: strain regulation compliant.
Falling silica on operator
Le problème
Ceiling fines fall on face: immediate OEL 0.1 mg/m³ exceedance.
Sept Tools
IU33 Longopac HEPA H13 source capture 65 l/s: exposure divided by 50.
Trace deviation under fatigue
Le problème
Ceiling chase manual: trace deviates after 30 min, double patching cost.
Sept Tools
Articulated arm guiding plus constant torque: clean trace in series.
Fixed balancer limited mobility
Le problème
Fixed compensator: work limited to 2 m², constant repositioning.
Sept Tools
Articulated arm plus Eland trolley IP65: full mobility across entire surface.
MSD absenteeism improvised set
Le problème

Frequently asked questions
Your questions, answered
Why a dedicated ceiling set?
Manual ceiling grooving quickly hits physical limits: raised arms, weight of the Desman, cumulative fatigue. A dedicated set with articulated arm and Eland trolley turns this punishing operation into a precise motion sustainable over a full day. The gains in throughput and ergonomics justify the investment for tertiary electricians and plumbers.
How does the articulated arm absorb the weight?
The articulated arm is a mechanical balancer that compensates for the weight of the Desman RAI102822 at all times, regardless of machine position. The operator only has to guide the feed without carrying the load. Same principle as the Gecko balancers for grinders, adapted to grooving.
What is the maximum ceiling depth?
The Desman RAI102822 reaches 35 mm in a single pass, sufficient for almost all ICTA conduits, multilayer tubes and standard cable runs. For greater depths, two successive passes are recommended.
Can reinforced concrete be grooved in the ceiling?
Yes, with suitable diamond blades. On dense reinforced concrete ceilings, throughput is roughly 25% lower than on a standard concrete ceiling. Radar rebar detection is recommended to avoid snags.
Payback period for a tertiary electrician?
For an electrician running regular tertiary renovations with recessed ceiling networks, the ceiling grooving set pays back in 6 to 10 months. Payback comes from time savings, elimination of MSD-related absenteeism, and silica OEL compliance that avoids labour inspectorate penalties.
