Abstract
Abstract A wall drainage system for protecting foundations and basement walls from water contact and seepage and including a water-impermeable synthetic resin backing plate adapted for securement to a surface to be protected and defining drainage channels along one side thereof facilitating drainage of water downwardly along the backing plate through the channels. A water-permeable synthetic resin strainer film is secured to the backing plate across the drainage channels. A synthetic resin water-receiving footer structure is connected to the lower end of the backing plate and includes a foraminous, synthetic resin bead pack and a perforated drainage pipe at least partially surrounded by the bead pack.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
134 words
A wall drainage system for protecting foundations, basement walls and the like comprising: a water-impermeable synthetic resin backing plate having a first side adapted for securement to a surface of the structure to be protected and defining drainage channels along a second side thereof opposite said first side; a water-permeable synthetic resin strainer film secured to the backing plate across said drainage channels to prevent dirt from clogging said channels; and a bead pack assembly connected to the lower portion of said drainage plate for receiving water from said drainage channels, said bead pack assembly including: a plurality of discrete synthetic resin beads peripherally bonded to each other to form a porous bead pack; and a perforated drainage pipe below, and at least partially surrounded by, said porous bead pack for receiving water therefrom.
Claim 2
Dependent Claim
134 words
A wall drainage system for protecting foundations, basement walls and the like comprising: a water-impermeable synthetic resin backing plate having a first side adapted for securement to a surface of the structure to be protected and defining drainage channels along a second side thereof opposite said first side; a water-permeable synthetic resin strainer film secured to the backing plate across said drainage channels to prevent dirt from clogging said channels; and a bead pack assembly connected to the lower portion of said drainage plate for receiving water from said drainage channels, said bead pack assembly including: a plurality of discrete synthetic resin beads peripherally bonded to each other to form a porous bead pack; and a perforated drainage pipe below, and at least partially surrounded by, said porous bead pack for receiving water therefrom.
Claim 3
Dependent Claim
22 words
A wall drainage system as defined in claim 1 wherein said backing plate is closed cell polystyrene in a rectangular parallelepiped configuration.
Claim 4
Dependent Claim
34 words
A wall drainage system as defined in claim 1 wherein said bead pack includes upper and lower portions positioned above and below said drainage pipe, respectively, and together enclosing and surrounding said drainage pipe.
Claim 5
Dependent Claim
22 words
A wall drainage system as defined in claim 1 wherein said resin beads range in size between pea size and peanut size.
Claim 6
Dependent Claim
136 words
A building structure comprising: a vertically extending sub-grade wall projecting down into the earth; a footing supporting the wall; a protective wall drainage system including: a flat, rectangularly configured drainage plate extending downwardly along the wall to a location adjacent the footing and having one side surface bonded to the wall to position the drainage plate between the wall and the earth; means defining earth-free drainage channels along a second side of said plate opposite said first side facilitating gravitational drainage of water downwardly along said second side; and a bead pack of multiple, discrete, interbonded synthetic resin beads connected to the lower end portion of the drainage plate for receiving water and having one side abutting said footing; and a perforated pipe for receiving water percolating through said bead pack to the lower side thereof.
Claim 7
Dependent Claim
136 words
A building structure comprising: a vertically extending sub-grade wall projecting down into the earth; a footing supporting the wall; a protective wall drainage system including: a flat, rectangularly configured drainage plate extending downwardly along the wall to a location adjacent the footing and having one side surface bonded to the wall to position the drainage plate between the wall and the earth; means defining earth-free drainage channels along a second side of said plate opposite said first side facilitating gravitational drainage of water downwardly along said second side; and a bead pack of multiple, discrete, interbonded synthetic resin beads connected to the lower end portion of the drainage plate for receiving water and having one side abutting said footing; and a perforated pipe for receiving water percolating through said bead pack to the lower side thereof.
Claim 8
Dependent Claim
39 words
A building structure as defined in claim 5 wherein said channel defining means comprises a water-permeable sheet secured to said second side to protect said second side from water contact, and projecting to, and secured to, said bead pack.
Claim 9
Dependent Claim
102 words
A bead pack assembly for providing a water drainage path adjacent a subgrade structural member comprising: a plurality of discrete synthetic resin beads bonded to each other at peripheral contact points to form a water permeable bead pack body, said body having an upper side and a lower side, and said lower side of said bead pack defining a pipe receiving recess; a perforated pipe in said recess with the perforations therein positioned to receive water from said bead pack body; and means attached to said bead pack body for locating said body adjacent the lower portion of a subgrade structural member.
Claim 10
Dependent Claim
102 words
A bead pack assembly for providing a water drainage path adjacent a subgrade structural member comprising: a plurality of discrete synthetic resin beads bonded to each other at peripheral contact points to form a water permeable bead pack body, said body having an upper side and a lower side, and said lower side of said bead pack defining a pipe receiving recess; a perforated pipe in said recess with the perforations therein positioned to receive water from said bead pack body; and means attached to said bead pack body for locating said body adjacent the lower portion of a subgrade structural member.
Claim 11
Dependent Claim
52 words
A bead pack assembly as defined in claim 7 wherein said locating means comprises a water permeable strainer film having a first portion extended along one side of said bead pack body and secured thereto, and a second portion adapted for securement to a backing plate mounted on the subgrade structural member.
Claim 12
Dependent Claim
46 words
A bead pack assembly as defined in claim 7 wherein said locating means comprises a neck formed on said bead pack body and including discrete synthetic resin beads, said neck having a configuration to fit over a footing forming a part of said subgrade structural member.
Claim 13
Dependent Claim
25 words
A bead pack assembly as defined in claim 7 wherein said synthetic resin beads range in size from about pea size to about peanut size.
Claim 14
Dependent Claim
52 words
A bead pack assembly as defined in claim 10 wherein said locating means comprises a water permeable strainer film having a first portion extended along one side of said bead pack body and secured thereto, and a second portion adapted for securement to a backing plate mounting on the subgrade structural member.
Claim 15
Dependent Claim
44 words
A bead pack assembly as defined in claim 7 and further characterized as including a second and lower bead pack body positioned below said perforated pipe and including a recess in the upper side thereof for receiving and supporting a portion of said pipe.
