What are Exterior Seals?
Exterior seals are normally used in external environments where both movement and weatherproofing are major considerations. Typically such
exterior seals are used in expansion gaps up to 100mm wide and are installed in floors/decks, walls and roof applications. Some joints in these
ranges are epoxy bonded into place whilst others seals are compressed and squeezed into position in the structural gap. Most of the seals included
are suitable for both pedestrian and vehicular loading.

What are Heavy-duty Expansion Joints?
A number of heavy-duty expansion joints are noted in the React Architectural Expansion Joint section, however most of these are designed for
occasional load from heavily laden vehicles. The joints in this section, however, have been specifically designed to withstand repeated loading
from such traffic and are suitable for use in car park decks, service and access areas and highway bridges. Like exterior seals, these joints are
normally used in external environments where both movement and weatherproofing are major considerations. The heavy-duty expansion joints
included in this section of the catalogue can be used in expansion gaps up to 216mm wide.

Are there any Standards or Norms that apply to Exterior Seals and Heavy-duty Expansion Joints?
Two widely recognised International Standards govern the impact of vehicular loading on joints, namely:
DIN 1055: Part 3: Loading of Fork Lift Trucks and Standard Vehicles
DIN 1072: Standard Moving Loads
Whilst the first of these considers loads applied by forklift loading upon joints and other floor components, the latter defines loading on bridges
and highways. These Standards are recognised as the most rigorous of their type and define loading magnitudes, vehicle types, individual wheel
loads and wheel contact areas from which the load rating for heavy-duty expansion joints is derived.
