A method of applying a chemical anchoring adhesive to the interior of a borehole includes the steps of providing a highly viscous, self-contained slug of chemical anchoring adhesive, inserting the slug into the borehole, providing an anchor pin, and driving the anchor pin into the borehole using a driving tool that imparts rotary motion to the anchor pin. The adhesive slug includes a first part having a first color and including a resin, and a second part having a second color different from the first and including a curing agent. The rotary motion of the anchor pin mixes the first and second parts together to form a substantially homogeneous composition having a third color different from the first and second colors. The visual indication provided by the third color notifies the worker when the mixing is complete, saving time and money at the construction site while minimizing the occurrence of defective or insufficient mixing.

A rope of chemical anchoring adhesive useful in heavy construction applications includes first and second parts in continuous contact along an interface extending the length of the rope. The first part includes a resin and has a highly viscous, putty-like consistency. The second part includes a curing agent and has a highly viscous putty-like consistency. The rope can be cut into slugs at the construction site which are sized according to the depth of the borehole, into which the anchor pin is driven.

A method of making and applying a chemical anchoring adhesive in the form of a highly viscous, self-contained rope or slug is provided. The rope or slug has an average cross-sectional area determined from a formula that takes into account the cross-sectional area of a borehole, the average cross-sectional area of an anchor pin to be inserted into the borehole, and a penetration factor which reflects penetration of the adhesive into the walls of the borehole. By selecting the proper area for the anchoring adhesive, the rope can be cut into slugs having depths equal to the depths of boreholes. When the slugs are inserted into the boreholes, and anchor pins are driven, the amount of adhesive provided by each slug will be just enough to completely fill the interstitial spaces between the anchor pin and inner wall of the borehole, accounting for penetration of some adhesive into the borehole wall.

A chemical anchoring adhesive having a solid, putty-like consistency includes two parts in direct contact with each other along an interface. The first part includes about 20-45% by weight of an epoxy resin, about 10-40% by weight of a first particulate filler having an oil absorption value of at least about 30, and about 40-65% by weight of a second particulate filler, at least about 70% of which has a U. S. Sieve size between 16 and 45. The second part includes about 5-20% by weight of an aliphatic amine compound, about 0. 1-15% by weight of a tertiary amine compound, about 1-23% by weight of a first particulate filler having the oil absorption described above, and about 52-87% by weight of a second particulate filler having the U. S. Sieve size described above.

A highly stretched film has permanently heat-sealed edges that are nearly invisible. A folding apparatus folds the edge portions of a film to form folded edges. The folded film then is passed through a bridle mechanism having two heated rolls. A series of nips apply pressure to the folded film as it is heated by the heated rolls. The nip pressure, combined with the heat imparted by the heated rolls, causes thermal welding of the folded edges resulting in permanent heat-sealed edges. Because the film edges are folded prior to the hot-stretching, the hot stretch process performs dual functions of stretching the film and heat sealing the folded edges. The resulting stretched film has permanently heat-sealed edges that do no separate, and which prevent tearing of the film edges during subsequent processing and use.

A film wrapper for use in storing slugs and ropes of chemical anchoring adhesive includes an outer metallized polymer layer and a heat seal layer. The metallized polymer layer protects the chemical anchoring adhesive from premature reaction by providing a barrier to oxygen and light. The heat seal layer may also act as a moisture barrier layer. The chemical anchoring adhesive is divided into slugs of appropriate size for insertion into boreholes and cementing of anchor pins in the boreholes.

A chemical anchoring adhesive includes a first part having a viscosity of about 200,000 to about 4,000,000 centipoise and a second part having a viscosity of about 200,000 to about 4,000,000 centipoise. The chemical anchoring adhesive can be in the form of a slug or rope. The first and second parts are directly joined along an interface, which may extend the length of the slug or rope. The first part includes a resin and a particulate filler of a type and amount required to achieve the desired viscosity. The second part includes a curing agent and a particulate filler of a type and amount required to achieve the desired viscosity.

A chemical anchoring adhesive includes first and second parts each having a highly viscous, putty-like consistency. The first and second parts are joined directly to each other along an interface. The first part includes a resin, and the second part includes a curing agent. The anchoring adhesive does not require separate encapsulation of one or both parts, and can be formed and cut to desired sizes and quantities at any stage before insertion into a borehole.
