The settling of new construction may open cracks, particularly at places of stress concentration such as the intersection of floor slabs and upstanding footings and walls. In some instances, the interruption of a pour or the interval between pours will result in poor bonding to produce a leak. Such leaks become troublesome after heavy rains or tides which raise the water table above the foundations to subject them to hydrostatic pressure. While interior sump pumps may remove such leakage, damp with resulting rot, mildew, odors, and the like render leaking basements unfit for residential or commercial purposes.
The conventional method of waterproofing existing foundations against hydrostatic pressure involves boring holes or excavating to pump clay, plastics, foam, or the like to block leakage paths through the wall and between the wall and the footing. Leaks from below passing between the edge of the floor and the wall or footing require breaking up the concrete floor slab adjacent to the wall or footing to dig a drainage ditch for coarse fill. A new border of the floor slab must then be poured and a sump pump or other drainage provided for the ditch. This conventional method is very costly and is not always effective.
SUMMARY OF THE INVENTION Cracks in flat surfaces are cut out and a flat strip is bonded over them and cracks in corners have a flat strip bonded at an angle in the corner so that the strips in each case form longitudinal channels extending along the cracks. Fittings are in serted in the strips and air is pumped into the channels to determine the amount of leakage through each section of crack. A sealer is prepared with a higher viscosity and other desired properties for cracks determined to have higher leakage therethrough. Low-viscosity sealer is prepared for cracks which have a slight leakage therethrough. The prepared sealers are then pumped under pressure through the fittings into the channels to fill and seal the cracks.
The process of this invention is far more economical and effective than conventional sealing techniques. When epoxy and like sealers are used to cure and cast in place within masonry cracks, the process of this invention actually serves to strengthen the masonry so sealed.

DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in FIG. 2, conventional basement construction provides a footing 10 which supports a foundation wall 11 which is usually poured to be keyed in place by a tongue 12 and groove 13. A floor slab 14 is poured abutting the footing l0 and wall 11. If the ground water level 15 rises above the floor slab 14, the most common leakage paths will be at 15 between the wall 11 and the footing l0 and at 16 at the edge of the floor slab 14.
As shown in FIG. 3, the conventional waterproofing of such basement construction is a costly and difficult process. Through exterior drillings 17 or ditching (not shown), waterproof material 18 is applied to seal the outside of footing l0 and wall 11. To seal the edge of floor slab 14, its outer edge must be taken up and a new edge 19 poured in place. This is usually so unsatisfactory, since further settling and working will cause new cracks, that a rubble filled drainage ditch 20 must often be provided with a drainage means such as a sump pump.
As shown in FIG. I, the waterproofing process of this invention is more effective and much less costly. To seal a corner between a floor slab l4 and a wall 11, the masonry surfaces are first cleaned in the area. Grinding may be required when the surfaces are degraded or coated with paint or other material. The area may be further cleaned by being soaked with muriatic acid or the like to attack fine particles. After cleaning, a strip 22 about one to 2 inches wide is laid at an angle and taped in place with fiberglas tape or the like. The strip 22, temporarily held in place by the tape 23, defines a channel 24 with the corner. A high penetrating epoxy mixture is applied to the area above and below strip 22 to penetrate and bond as shown at 26 and 27.
A suitable mixture of this purpose would be an epoxy cement in which two chemical compositions are mixed just prior to application, one composition reacting with the other to form a cured plastic after a predetermined time.
The addition of suitable known compositions will cause the epoxy system to become thixotropic. Continuous brushing or rolling will then lower viscosity and improve penetration into the cleaned concrete or masonry. The proportions of the epoxy system or mixture are varied depending upon the condition of the masonry, its porosity, the ambient temperature, moisture conditions, etc. Maximum bonding power should be obtained to provide astrong channel 24 for the purpose which will be described.
After the epoxy penetration and bonding has been assured at 26 and 27, a more viscous mixture is applied over the entire comer area including strip 22 and tapes 23. Fiber glass cloth is applied and impregnated with another coat of epoxy to build up a strong layer 29 over channel 24.
One of the two fittings 30 in each channel section 31 is plugged and air is pumped into the other. By measuring the volume of air at a given pressure during a given time interval passing through a leaking crack and escaping from a channel section 31, the effective cross-sectional area of a leak may be estimated. In addition, the flow of compressed air will blow water from the leakage area to allow the leak to be better sealed.
If a small amount of air escapes indicating a small effective leak area, a viscous sealer fluid is prepared. If a larger amount of air escapes indicating a larger effective leak area, a more viscous sealer fluid is prepared. Larger leaks also require a sealer with a shorter cure time. Temperature and other conditions should be taken into account in preparing a sealer for a given channel section 31. One method of measuring the amount of air that passes through a given leak to estimate the effective leak area would be to prepare a small compressed air chamber 60 with a pressure indicator 61 thereon. The chamber would then be charged with compressed air at a given pressure. The chamber would be connected to a fitting 30 with hose 62 and valve 63 as shown in FIG. 5 and airflow through the leak would be measured by measuring the time it took for air pressure in the chamber 60 to drop to a given lower pressure on the pressure indicator 61.
The sealing mixture, which is preferably an epoxy casting mixture, is pumped into one fitting 30 of a given section 31. The other fitting 30 in that section 3l may be removed or opened to allow air trapped in channel 24 to escape. Pressure may be maintained on the casting or sealing mixture during its cure period to offset shrinkage. As may be seen in FIG. 1, the sealer flows where needed in areas and 16 and sets or cures to form or castin place a solid seal 33 which extends into channel 24. It has been found that an epoxy bond or cast in a masonry crack is stronger than the original material and thus may actually strengthen a moistureproof structure.
As shown in FIG. 4, cracks 40 in flat surfaces are cut out at 41. In the manner which has been described, a strip 42 is bonded with epoxy and fiberglass cloth over cutout crack 41 to form a channel 43. The strip 42 and the epoxy and fiberglass cloth 44 form a wall of channel 43 which is bonded to floor slab 14. Air and a suitably prepared sealer are pumped through drilled and tapped apertures 45 at each end of crack 40 to seal it in the manner which has been described.
FIG. 6 shows a crack 46 in a wall 11 cut out to form a channel.43 covered by a strip 42 which is bonded to wall 11 by epoxy and fiber glass cloth 44. A sealer 50 has been pumped into channel 43 to cast in place and sea] crack 46.
FIG. 7 shows a sheet metal strip 50 having perforations 51 in its edges. An epoxy fluid may be painted on each side of a cut out crack and a strip 50 pressed down over it. Epoxy will flow up through the perforations 51 to cure and bond the strip 50 in position to form a wall of a channel to be used in the manner described.
FIG. 8 shows a sheet metal corner strip 53 having a solid center portion 54 and two angled side portions 55 and 56 containing perforations 57. When a corner is prepared and coated with an epoxy cement adjacent to the corner, strip 53 may be pressed in place with side portion 55 against a wall and side portion 56 against a floor. The epoxy will flow through the perforations 57 to cure and bond the strip 53 in place.
The wall forming strips may be of any desired material. Casting or sealing materials may be varied depending upon specific conditions. Polyesters may be substituted for both channel construction and sealing and casting. Butal and silicone rubbers may be used for sealing.
