Concrete Wall TV Mounting Guide¶
Concrete walls provide the strongest possible TV mounting surface but require specialist tools and fixings. This guide covers concrete wall identification, SDS drilling techniques, resin anchor and shield anchor selection, and UK building regulations for concrete wall mounting.
Identifying UK Concrete Walls and Choosing Fixings¶
Concrete walls are common in UK modern flats built since the 1960s, tower blocks, and new-build homes. Unlike brick, concrete is monolithic with consistent density throughout. Types include poured concrete (150-300mm thick), precast concrete panels (100-200mm), and aerated concrete blocks. Poured concrete requires an SDS drill with carbide-tipped masonry bits -- standard hammer drills overheat and struggle. Drilling takes 30-60 seconds per hole. Dust control is essential: use a vacuum attachment or wear an FFP3 respirator. COSHH regulations govern silica dust exposure in the UK. For TVs under 25kg use expanding sleeve anchors (M8, £3 each at Screwfix). For TVs over 25kg use two-part polyester resin anchors (M10, £5-£8 per hole). Fischer FIS VL 300T resin cartridge costs £25 from Toolstation and provides 15-20 anchorings at 80mm depth.
Installation Procedure for Concrete Walls¶
Step 1: Mark bracket position with TV centre at 105-115cm from floor using a laser level. Step 2: Drill to correct depth using the depth stop on the SDS bit. For resin anchors drill 10mm diameter at 80mm depth. For sleeve anchors drill 12mm at 70mm depth. Step 3: Clean the hole thoroughly -- wire brush in and out 5 times then blow dust with a bulb pump. Step 4: For resin anchors inject resin to fill 2/3 of hole depth then insert threaded stud with a twisting motion. Step 5: Allow cure time -- 30 minutes at 10°C typical UK indoor temperature. Step 6: For sleeve anchors insert anchor and tighten to 15-20 Nm using a torque wrench. Step 7: Attach wall plate and tighten nuts. Step 8: Mount TV onto wall plate and engage the locking mechanism. Concrete installations are permanent -- repositioning requires filling old holes with repair mortar. Resin anchor kits from Fischer cost £25-£35. Hire an SDS drill from HSS Hire for £30 per day. Always check for hidden pipes and cables using a detector before drilling into concrete walls.
Specifications and Comparison¶
| Concrete Type | Thickness | Recommended Fixing | Max TV Weight | Drill Bit Size |
|---|---|---|---|---|

| Precast concrete panel | 100-200mm | M8 resin anchor | 50kg | 8mm SDS |
| Precast hollow-core panel | 100-200mm | M8 sleeve anchor | 40kg | 10mm SDS |
| Aerated concrete block | 100-150mm | Fischer Gasbeton anchor | 30kg | 8mm SDS |
| Reinforced concrete | 200-400mm | M10 resin anchor | 100kg | 12mm SDS |
FAQ¶
- Do I need planning permission to mount a TV on a concrete wall in a UK flat?
- No, TV mounting is normally permitted development. However check your leasehold agreement -- some UK flats prohibit drilling into structural concrete walls. Consult building management before drilling.
- Can I use standard wall plugs in concrete?
- No, standard plastic wall plugs like Fischer UX are designed for brick or blockwork. Dense concrete requires expansion anchors or resin anchors. Standard plugs will not grip properly in poured concrete.
- Is an SDS drill necessary for concrete TV mounting?
- Yes for poured and reinforced concrete. A standard hammer drill will overheat and struggle. Use an SDS or SDS-Plus drill with carbide-tipped masonry bits. Hire from HSS Hire for £25 per day if you do not own one.
- How far apart should concrete wall fixings be for a TV mount?
- Standard wall plates have fixing points 200-400mm apart horizontally and 100-200mm vertically. Use all available fixing points. A minimum of four fixings is recommended for TVs over 32 inches.
- What is the correct torque for concrete wall TV mount fixings?
- M8 resin anchors require 15-20 Nm. M10 require 25-35 Nm. Use a torque wrench. Overtightening can strip the resin bond or snap the threaded rod. For sleeve anchors follow manufacturer specifications typically 10-15 Nm. For more information see our Brick Wall TV Mounting Guide.
