FIXING HOLDS TO BRICK, BLOCK WORK,
STONE OR CONCRETE
The question we often get asked is can I put some of your
holds on the side of my house? The answer is usually yes as
long as you have a flat surface. On a similar vein the Beacon
has been involved with many school projects where bolt-on
holds have been fixed to playground and gym walls. This can
provide a low budget opportunity to provide a climbing wall.
If you are considering this type of wall you need to consider
the following points:
- Is your wall structurally sound, if there is any doubt
you should get a structural engineer to check it out. If
we are given full details of the proposed wall we can have
the check carried out by our structural engineer.
- Are there adequate flat areas to take bolt-on climbing
holds, if the surface is particularly uneven holds will
have a tendency to spin and may break on tightening.
- Are you able to drill into solid areas of wall. It is
possible to obtain good resin fixings in hollow materials
but it is far preferable if there are no cavities.
- If you are planning to provide roped climbing the structural
requirements are much higher and are governed by BS12572,
again we can give you advice on this
- This is a very economical way of getting a climbing wall
but will it be interesting enough. Bolt-on holds work best
on ply wood they can be moved around easily, the ply can
be textured and angle changes are possible.
If you decide to fix to brick, block work, concrete or stone
it is possible to use either internally threaded expansion
sockets or resin sockets. Resin bolts should be used for walls
that will be used by the public, although expansion fixings
will usually suffice for ‘home walls’.
Fixing expansion sockets
Expansion sockets are used for fixing holds to brick, block
or concrete walls, and holds used for this purpose will be
supplied with a thin rubber backing. To fix:
- Using a 12mm masonry bit, drill a 42mm deep hole, perpendicular
to the wall.
- Clear the hole thoroughly of dust.
- Tap home the expansion fixing using the ‘setting
tool’.
Fixing resin sockets
Resin fixings give stronger and more consistent fixing in
poor surfaces. These, and tubes of polyester resin, can be
purchased from The Beacon, and you will also need a mastic
'gun' for injecting the resin. To fix:
- Drill a hole (slightly longer than the fixing) perpendicular
to the wall surface with an 18mm diameter masonry bit.
- Clean the hole thoroughly - a bicycle pump and toothbrush
should do the trick.
- Inject the hole approx 2/3 full of resin.
- Carefully insert the sleeve ensuring that excess resin
is cleaned away.
- Allow 1 hour before mounting holds and a further 24 hours
before use.
