    Draining a concrete shell swimming pool

    I do not have as built data, the original plans filed by the owners then to the city for permit processing in 1992 was a one sheet plan related to the location, size of the pool/spa and the piping schematic of the pump/filter equipment. I have no idea how thick the concrete shell is, or how it...

    Draining a concrete shell swimming pool

    Not sure of the best forum for this, a bit of structure a bit of drainage and a bit of soil... On 4/12/2023, a historic flash flood happened in south Florida, where I live, 26 inches of rain within 12 hours, and most of it within 6 hours. Water so deep cars floated away, I live next to a river...

    "The answer is: do not bury the post in concrete. Rather embed a metal post base in the concrete. Then install the post on the base." Local code requires posts embedded in concrete. I see what you are suggesting is if allowed, I can keep the concrete base and keep changing out the post base...

    "What you have done is called cement stabilization. Usually about an 8:1 ration of soil to cement. Common in road building for subbase lifts." I have no idea what kind of ratio I used or even if it's sound except for my quick experiment it did seem like it worked. I will keep the 8:1 ratio in...

    "When you backfill a hole you have do it in stages (lifts). For a 18" diameter hole fill maybe 8-10" at a time and compact, then fill the next, and so on. You soil must be nearly all sand, correct? You really need to use posts that the bugs won't eat and that won't rot." Yes soil is very sandy...

    thread194-495078 This is a continuation of a previous thread (now closed) on solution to replace a wood fence post 4X4 or 6X6 at the same location. I have resolved the issue, somewhat but like to get some feedback, in addition, I like to reply to some of the previous suggestions. The issue at...

    small wood bridge replacement

    Would like to know if anyone has any opinion on joist tape used to wrap around the top side of lumber to minimize moisture penetration on deck substructure. Does it really work or is that a gimmick, seems to be popular in many locales now.

    small wood bridge replacement

    The bridge is only 17' long, there is a mid span support. Excluding the end support each span is less than 7 feet. The old version is three 2X6 spaced 18" apart and it didn't feel bouncy before it rotted out even when 3 people walk on it with a fully loaded wheel barrow of river rocks. I am...

    small wood bridge replacement

    It does flood here, but not to the point of lifting the bridge. The bridge is surrounded by many concrete boulders so it will not float away. If it does get lifted it will just drift in place.

    small wood bridge replacement

    I looked into it but many railroad ties are soaked with creosote. This may leach into the pond and affect the fish in the pond so I don't want to risk that. I have used railroad ties for planting borders last a long time and very heavy duty as long as it's not bordering edible veggies.

    small wood bridge replacement

    The marine grade lumber you are referring to, I believe is the CCA treated lumber. Before 2004 most pressure treated lumber are CCA treated. They found arsenic agents in that so after 2004 the new PT lumber are ACQ treated, however those does rot quicker, much quicker and also they corrode...

    small wood bridge replacement

    I have a small wood bridge over a pond at my property that needs replacement. The existing structure has a span of 17 feet, 42" wide. The deck are all 2X4s, the substructure is three pieces of 2X6s at 0, 20", 40". The 2X6s are sitting on grout filled concrete blocks at each end, and a stack...

    Replacing wood fence posts at the same location

    That will not fly where I am. I am in a historic district where materials used are very restricted. For fences it's basically wood or wrought iron, but wrought iron is not typically usable for a privacy fence because of it's transparency, and wrought iron fences of many configurations are not...

    Replacing wood fence posts at the same location

    I probably worded it poorly, I did do small lifts and compact as hard as I can. I said 4" lifts but more or less I was doing two to three shovels, then compact with the 2X4 into the hole all the way around, then I ran water into the hole to further settle the soil, the repeat until the hole is...

    Replacing wood fence posts at the same location

    I do mostly drainage design. I have hand steel tampers in 8X8 sizes. But yes I prefer to use a piece of 2X4 because it seems to be more effective when the hole size is irregular shaped and small, because it can be used to pound hard at various angles to get things as tightly packed as...

    Replacing wood fence posts at the same location

    I am not sure I follow the question. The gate posts are rotted at the base where they meet ground, I would say probably 50% of the materials are gone. The gates are currently not operational, because they are sitting on concrete blocks so they stay level but unmovable. I have several 2X4s...

    Replacing wood fence posts at the same location

    Let me clarify, the post is not supporting a gate 8'+ wide. It is a 10' wide double gate, so two 5' gate, each mounted on their respective 6X6 post.

    Replacing wood fence posts at the same location

    The issue is not the actual removal. I can get help to tease out the anchor and post, even pull it out with a truck, or whatever. The problem is the current anchor is already 18" to 20" in diameter. It is simply too big. These are gate posts, so in between them is a driveway, I would have to...

    Replacing wood fence posts at the same location

    I have been using the ground contact pressure treated wood which I understand is one step better than the regular above ground PT lumber. I did not know about the marine grade lumber. I will check into it. Thank you.

    Replacing wood fence posts at the same location

    These are 6X6 posts with 5' gates hanging on them so stability is important to prevent leaning gates. I have in the past tried digging the wood rot out, in my case it didn't work because it actually got a lot harder once the loose pieces are out. The post is only rotted at the point where the...
