Double Flange, Double Seal Earth Seals
The earth rod seal is fitted when the earth rod connection is below the
water level and where there is a possibility of water entering the
inspection housing from below ground. The earth seal is particularly
useful where internal earths are required such as in a basement building.
They can be adapted to suit our full range of earth rod diameters. The
seals are used in conjunction with the Exoweld heavy duty earth
inspection housing It BEINSPITHD.

EXOWELD EARTH ROD SEAL (ES002 DOUBLE FLANGE)
INSTALLATION PROCEDURE
Exoweld Earth Rod Seal ES002 has been designed for use in concrete slabs of any thickness. It can be used with Plastic Pit,
Concrete Pit or no pit at all. The seal will withstand water pressures in excess of 80 psi, which is far in excess of site conditions.
Under no circumstances should the main concrete slab be shuttered out and the earth seal fitted at a later date. The final
performance of this product is dependent on its integrity with the surrounding concrete “Any ingress/accumulation of water from
anywhere other than around the earth rod is the responsibility of the installer”. It is essential that the earth seal flange is free from
any debris, stones, grease, and paint before pouring of the concrete takes place. The concrete should be fully compacted to
ensure sealing. INSTALLATION
The following steps are carried out after the earth rod has been driven allowing sufficient rod length for top flange to be fitted.
1. STEP 1 (CHECK ALL COMPONENTS ARE PRESENT)
This ES002 kit includes 2 x identical flanges, 2 x identical seals and 1 x Allen key
2. STEP 2 (CHECK EARTH ROD AND SEAL ARE COMPATIBLE)
Check the earth rod size is compatible with the specially designed multi purpose seal. The seal has special
inserts that are pushed out to suit the size of the earth rod in use.
3. STEP 3 (POSTION BOTTOM FLANGE)
Position the bottom flange over the earth rod and guide down to rest on the concrete. Ensure that there are no
obstructions under or within the flange (stones, broken concrete, and debris)
4. STEP 4 (APPLY ADHESIVE MASTIC)
If a waterproof membrane is in place the membrane should be adhered to the bottom face of the flange using
adhesive mastic. The mastic layer should be applied in a heavy circular formation so that the grooved underside
of the flange can ‘bed’ down without causing radial breaks and leakage paths.
5. STEP 5 ((POSTION THE BOTTOM SEAL)
Position the bottom seal (NOT tightened) over the earth rod and guide down to position in the locating hole of
the flange.
6. STEP 6 (TIGHTEN THE BOTTOM SEAL)
Tighten the caphead screws using Allen key provided. It is IMPORTANT that the screws should be tightened
gradually / sequentially. Gently tighten each screw initially to take up any lose play then proceed to tighten
opposing screws with an equal number of turns until hand tight. It is important to follow the correct sequence
and tighten opposing screws and not screws next to each other, this will ensure the seal ‘beds’ in evenly.
7. STEP 7 (POUR CONCRETE)
Main concrete slab can be poured to desired depth. Ensure sufficient earth rod is left exposed to fit top flange
and shuttering for plastic or concrete pit “with lid fitted” to prevent concrete ingress.
8. STEP 8 (POSTION TOP FLANGE)
Position the top flange over the earth rod and guide down to rest on the concrete. Ensure that there are no
obstructions under or within the flange (stones, broken concrete, and debris)
9. STEP 9 (POSITION TOP SEAL AND TIGHTEN)
Position the top seal (NOT tightened) over the earth rod and guide down to position in the locating hole of the
flange. Tighten top seal using same procedure as step 6
