A rubber bullet trap needs 4 BRB-200 blocks per square metre of trap face: each block is 500 × 500 × 200 mm and about 42.5 kg, so about 170 kg/m² before the steel backing. Anti-ricochet lining needs 1, 2 or 4 tiles per square metre, depending on the format, at about 34.4 kg/m² (40 mm) or 38.9 kg/m² (45 mm); 100 m² of 45 mm tiles weighs about 3.9 t. BulletTrap Baltic returns the counts and delivery weight for the range dimensions you send and ships from Lithuania across the EU.

Dimensional tolerance ±2 mm. Mass per tile is the mass per square metre divided by the number of tiles in one square metre. Block density 850 kg/m³.
How many ballistic rubber blocks does a bullet trap need?
Four per square metre of trap face, because one BRB-200 block covers 0.5 × 0.5 m.
Count the blocks row by row, so that a part block at the edge is counted as a whole one:
- Blocks across = trap width in metres ÷ 0.5, rounded up.
- Rows = trap height in metres ÷ 0.5, rounded up.
- Blocks = blocks across × rows.
- Mass = blocks × 42.5 kg.
A trap face 5 m wide and 2 m high takes 10 × 4 = 40 blocks, about 1.7 t of rubber. The count covers the rubber face only: the armoured steel plate behind it is a separate item, and how thick it should be is explained in steel backing plate thickness for a bullet trap. How the block and the plate work together, with the test results: bullet traps.
How many anti-ricochet tiles per square metre?
One, two or four: a 1000 × 1000 mm tile covers 1 m², a 500 × 1000 mm tile 0.5 m² and a 500 × 500 mm tile 0.25 m².
- Tiles along a surface = surface length ÷ tile length, rounded up.
- Tile rows = surface height (or width, for a ceiling) ÷ tile width, rounded up.
- Tiles = tiles along × rows; repeat for each surface.
- Mass = lined area in m² × 34.4 kg (40 mm) or × 38.9 kg (45 mm).
The format changes the number of pieces and joints, not the mass per square metre. Thickness, 40 or 45 mm, changes the mass and the impact angle from which a bullet stays in the tile; the angles by calibre are on how to stop ricochet in an indoor range.
How much does the rubber for a shooting range weigh?
About 170 kg per square metre of block trap face, 34.4 kg per square metre of 40 mm lining and 38.9 kg per square metre of 45 mm lining.
| Quantity | BRB-200 blocks | BRT-40 tiles, 40 mm | BRT-45 tiles, 45 mm |
|---|---|---|---|
| 1 m² | about 170 kg | about 34.4 kg | about 38.9 kg |
| 10 m² | about 1.7 t (40 blocks) | about 344 kg | about 389 kg |
| 100 m² | about 17 t (400 blocks) | about 3.44 t | about 3.9 t |
The weight matters three times: for the freight, for the floor that carries a block trap, and for the ceiling or baffle carrier that holds tiles overhead. Why weight drives the delivered cost: what a rubber bullet trap costs, item by item. Tiles on baffles instead of a full ceiling: shooting range baffles.
Which surfaces of an indoor range are lined, and how are they measured?
Up to four: the trap face, the side walls, the ceiling and the floor between the firing line and the trap.
As one published reference, the indoor range requirements of the Estonian Centre for Defence Investment (RKIK, Annex 2, edition of 05.11.2025) ask for bullet-resistant walls, ceiling and floor in front of the firing line (point 8) and a ricochet-resistant floor over the whole length of the range (point 48). They set the minimum length at the shooting distance plus 5 m (point 18) and the minimum clear height at 2.20 m (point 19). These are a state customer’s technical requirements; the rules of your country and your range expert decide what is lined.
| Surface | Measure | Product |
|---|---|---|
| Trap face | Width × height of the trap | BRB-200 blocks, 4 per m² |
| Side walls | 2 × length from firing line to trap × height | BRT-40 or BRT-45 tiles |
| Ceiling | Length from firing line to trap × room width, or the faces of the baffles | BRT-40 or BRT-45 tiles |
| Floor | Length from firing line to trap × room width, if surfaced with tiles | BRT-40 or BRT-45 tiles |
In a new range the RKIK requirements place windows behind the firing line (point 64) and restrict doors and windows to the area behind the firing line and the side wall (point 55).
Example 1: how much rubber does a 4-lane 25 m indoor range need?
About 72 blocks and 300 m² of 45 mm tiles, roughly 14.7 t of rubber, for the example room below.
Example dimensions, chosen for the calculation and not a standard: 4 lanes, shooting distance 25 m, room 30 m long (25 m plus the 5 m RKIK minimum), 6.0 m wide and 3.0 m high. The trap face covers the full width and height; side walls and ceiling are lined over 25 m from the firing line to the trap with BRT-45 tiles in 1000 × 1000 mm.
| Surface | Dimensions | Area | Count | Mass |
|---|---|---|---|---|
| Trap face, BRB-200 | 6.0 × 3.0 m | 18 m² | 12 × 6 = 72 blocks | about 3,060 kg |
| Side walls, BRT-45 | 2 × 25.0 × 3.0 m | 150 m² | 150 tiles | about 5,835 kg |
| Ceiling, BRT-45 | 25.0 × 6.0 m | 150 m² | 150 tiles | about 5,835 kg |
| Total | 18 m² + 300 m² | 72 blocks + 300 tiles | about 14.7 t |
In 500 × 1000 mm tiles the same 300 m² is 600 pieces, in 500 × 500 mm it is 1,200 pieces; the mass does not change. Not included: steel backing plate, fixings, baffle carriers and floor.
Example 2: an 8-lane 25 m range with 40 mm tiles and a lined floor
About 144 blocks and 750 m² of 40 mm tiles, roughly 31.9 t of rubber.
Example dimensions: 8 lanes, shooting distance 25 m, room 12.0 m wide and 3.0 m high. Trap face over the full width and height; side walls, ceiling and floor lined over 25 m with BRT-40 tiles in 1000 × 1000 mm.
| Surface | Dimensions | Area | Count | Mass |
|---|---|---|---|---|
| Trap face, BRB-200 | 12.0 × 3.0 m | 36 m² | 24 × 6 = 144 blocks | about 6,120 kg |
| Side walls, BRT-40 | 2 × 25.0 × 3.0 m | 150 m² | 150 tiles | about 5,160 kg |
| Ceiling, BRT-40 | 25.0 × 12.0 m | 300 m² | 300 tiles | about 10,320 kg |
| Floor, BRT-40 | 25.0 × 12.0 m | 300 m² | 300 tiles | about 10,320 kg |
| Total | 36 m² + 750 m² | 144 blocks + 750 tiles | about 31.9 t |
Compare the two examples: doubling the lanes doubles the trap face and the ceiling (and the floor, where it is lined), but the side walls stay at 150 m², because their area depends on the range length and height, not on the number of lanes. Without the floor, example 2 is about 21.6 t.
What does BulletTrap Baltic need to calculate your quantities?
Eight items of data, most of them from the range drawing.
- Indoor or outdoor range.
- Shooting distance and number of lanes.
- Inner dimensions: length from the firing line to the trap, width, clear height.
- Surfaces to cover: trap face, side walls, ceiling or baffles, floor.
- Calibres fired, or the tile thickness already specified (40 or 45 mm).
- Tile format, if the substructure dictates one (500 × 500, 500 × 1000 or 1000 × 1000 mm).
- Columns, ducts or other elements inside the lined area.
- Delivery country and site.
From these BulletTrap Baltic returns the block and tile count, the delivery weight and the test reports ES-230403 and ES-240131 for the range file. If a damaged section has to be renewed later, see replace a damaged tile or the whole wall.
Questions about rubber quantities
How many ballistic rubber blocks per square metre?
Four. A BulletTrap Baltic BRB-200 block measures 500 × 500 × 200 mm, so four cover one square metre of trap face, at about 170 kg/m² before the steel backing.
How much does one ballistic rubber block weigh?
About 42.5 kg. The BRB-200 block supplied by BulletTrap Baltic is 500 × 500 × 200 mm of high-density SBR at 850 kg/m³. Forty blocks weigh about 1.7 t.
How many anti-ricochet tiles cover 100 m² of wall?
100 tiles in 1000 × 1000 mm, 200 in 500 × 1000 mm or 400 in 500 × 500 mm. In 45 mm the 100 m² weigh about 3.9 t, in 40 mm about 3.44 t. BulletTrap Baltic supplies all three formats in both thicknesses.
How much rubber does a 25 m indoor range need?
It depends on the width, height and which surfaces are lined. In BulletTrap Baltic’s worked examples, a 4-lane range 6 m wide and 3 m high needs about 72 blocks and 300 m² of 45 mm tiles, about 14.7 t; an 8-lane range 12 m wide with a lined floor needs about 144 blocks and 750 m² of 40 mm tiles, about 31.9 t.
Does the block count include the steel backing plate?
No. BulletTrap Baltic counts the rubber face only; the armoured steel plate behind the blocks is a separate item. In report ES-240131 from the Royal Military Academy (perpendicular shots, VPAM ARG Fassung 3 as the reference) the block alone was perforated; the projectile was stopped by the 500 HB steel plate behind it.
Does choosing 40 mm or 45 mm tiles change the count?
No, the count depends on the format. The mass changes: 34.4 kg/m² for 40 mm and 38.9 kg/m² for 45 mm, a difference of about 450 kg per 100 m². Thickness is chosen from the calibres fired and the angles in report ES-230403.
Which tile format should I choose?
A 1000 × 1000 mm tile gives the fewest pieces and joints, one per square metre. A 500 × 500 mm tile weighs about 8.6 kg in 40 mm and 9.7 kg in 45 mm, which is lighter to lift onto a ceiling. BulletTrap Baltic supplies 500 × 500, 500 × 1000 and 1000 × 1000 mm.
Does adding lanes increase the wall area?
No. Side-wall area is length × height × 2, whatever the number of lanes. Extra lanes widen the trap face, the ceiling and the floor; in BulletTrap Baltic’s examples, going from 4 to 8 lanes doubles the trap face and the ceiling and leaves the walls at 150 m².
Where does BulletTrap Baltic deliver the rubber?
BulletTrap Baltic ships from Lithuania across the EU, with no customs or import duty inside the EU. Deliveries to countries outside the EU are possible; the terms are set in the quotation.
