Buyers Guide


It is often necessary in tunnelling to enhance the strength properties and impermeability of the ground artificially in order to provide additional stability during construction or supplement the support capability of the permanent tunnel lining. Two basic methods are commonly available, namely injection grouting and strata reinforcement using ground anchorages and rockbolts. Though normally used during the construction of new tunnels, these methods are finding increasing use in the refurbishment of existing tunnels.
